AbstractThe project A Digital Resource for Developing Mathematics Teachers' TPCK is developing and conducting initial tests of a highly innovative interactive digital textbook to enhance middle grades mathematics teachers' understanding of core concepts in proportionality and their understanding of ways that technology can be used to enhance instruction. The project is led by professionals from SRI International with substantial contributions by mathematics educators at San Diego State University, San Francisco State University, the Singapore National Institute of Education, and the Center for Applied Special Technology (CAST).The digital textbook combines elements from SimCalc, Geometer's Sketchpad, and data analysis software to teach core ideas of proportionality from algebraic, geometric, and statistical perspectives. It also includes elements designed to help teachers see the connections among those uses of proportional reasoning and the ways that such tools can be used in classroom instruction with middle school students.The basic hypothesis of the project is that the proposed DynaBook will be a highly effective tool for mathematics teacher preparation and professional development and, ultimately, for classroom instruction of middle school students. Pilot tests in laboratory, teacher preparation, and professional development settings are providing initial empirical evidence about two core research questions:* In what ways does the DynaBook effectively support teacher learning of pedagogical and technological content knowledge?* Does the DynaBook foster teachers' understanding of the coherence and connectedness of middle school mathematics?This project explores very promising new forms of instructional materials with potential to transform the ways that we think about educational texts and teaching strategies.

AbstractThe project A Digital Resource for Developing Mathematics Teachers' TPCK正在开发和进行一种高度创新的交互式数字教科书的初步测试，以提高中年级数学教师对比例核心概念的理解，以及他们对技术可以用于增强教学的方式的理解。该项目由SRI International的专业人士领导，圣地亚哥州立大学、弗朗西斯科州立大学、新加坡国立教育学院和应用特殊技术中心（CAST）的数学教育工作者做出了重大贡献。数字教科书结合了SimCalc、Geometer's Sketchpad和数据分析软件的元素，教授代数、几何、几何、比例的核心思想和统计观点。 它还包括旨在帮助教师看到比例推理的使用之间的联系，以及这些工具可以用于课堂教学与中学生的方式的元素。该项目的基本假设是，拟议的DynaBook将是一个非常有效的工具，为数学教师的准备和专业发展，并最终为中学生的课堂教学。 在实验室、教师准备和专业发展环境中进行的试点测试为两个核心研究问题提供了初步的经验证据：* DynaBook以何种方式有效地支持教师学习 教学和技术内容知识？* DynaBook是否促进了教师对连贯性的理解， 中学数学的连通性该项目探索了非常有前途的新形式的教学材料，有可能改变我们对教育文本和教学策略的思考方式。
